Step-by-step explanation:

4πr²

if the diameter is 12742, then the radius is 6371

4π(6371)²

Answer:

510064471909788 m²

Step-by-step explanation:

diameter=12742  so the radius r=12742/2=6371=6371*1000=6371000

A=4πr²

A=4π(6371000)²

A=162358564000000π =510064471909788 m²

In June 2005, a CBS News/NY Times poll asked a random sample of 1,111 U.S. adults the following question: "What do you think is
Shtirlitz [24]

Answer:

The appropriate null hypothesis is H_0: p = 0.25

The appropriate alternative hypothesis is H_1: p < 0.25

Step-by-step explanation:

Exactly a year prior to this poll, in June of 2004, it was estimated that roughly 1 out of every 4 U.S. adults believed (at that time) that the war in Iraq was the most important problem facing the country.

At the null hypothesis, we test if the proportion is still the same, that is, of \frac{1}{4} = 0.25. So

H_0: p = 0.25

We would like to test whether the 2005 poll provides significant evidence that the proportion of U.S. adults who believe that the war in Iraq is the most important problem facing the U.S. has decreased since the prior poll.

Decreased, so at the alternative hypothesis, it is tested if the proportion is less than 0.25, that is:

H_1: p < 0.25

Which correlation coefficient will most likely describe the relationship between frequency of teeth brushing and the number of c
abruzzese [7]

Answer:

The correct approach is "-62". A further explanation is described below.

Explanation:

  • A dependent variable could be seen since the blackheads become triggered whenever some substance or material is deposited between some of the teeth.
  • Humans don't brush their teeth frequently, but there is still a significant possibility of decay, so cavities differ depending upon whether the specific teeth become brushed.
